Reusing storage bags with one-way valves
nixda
I have a bunch of used mylar bags with one-way valves from commercial roasters, holding about 1/2 lb each. I was wondering if there is anything that speaks against reusing them for degassing my own roasts. Would it make a significant difference to use new bags and seal them? Tentatively I would say reusing is fine, but I wanted to check if I am missing something.

BTW, where would one get fresh bags (not that I have a sealing iron...).

Sweet Maria's sells bags for a pretty low price, the only problem I see with reusing them is that coffee oils will coat the inside of the bag and eventually go stale, imparting a unpleasant flavor to your wonderful beans.
The bags from sweet marias have zipper tops, so you don't need a sealer anyways. You can also remove the valves and put them in mason jar lids.

I reuse these bags from Sweetmarias (or toastmasters). The come in 1/2 lb and 1 lb.
I don't really worry about coffee oils (I also infrequently roast as dark as FC+ and never darker). After many uses (?10 or 20 or more) the zippers tear and it gets thrown out.

It helps to open them with a little care to prevent premature destruction of the zipper.



edit for simplicity, there is no need to quote the post directly below the post...

Hi, Nixda.
Why degas in bags? I use jars - leave the lid loose for a day, then tighten it up.

Then they go in the dishwasher, and are ready for more coffee.

Mine are jelly jars and I've been using the same ones for about 5-6 years or so. Jars aren't as sexy but it's a dark closed cupboard and no one can see 'em. Saves a fortune and it's easy to pour the beans out.

I'm with John. I don't see an issue with reusing those bags but with Ball (or similar) jars you get near infinite uses out of them and can run them through the dishwasher.

I did it because of the one way valve (I thought it might be better for keeping the beans fresh) though you got me think maybe it doesn't matter much. I'm also wondering now if a lose ball jar lid would basically act as a one way valve anyway, pushing up when there's enough pressure and dropping down and mostly sealing when there's little pressure differential.

I let my roasts sit in a wire colander for the first 12-24 hours then to tightvac jars with the lids off for another 12-24 then capped up.

Not sure if this is the best way to do things but it seems to work for me as I can shake/toss the beans around in the colander to remove more chaff before putting them away

One can reuse the Mylar bags until the seal is no longer working
The bags can also be washed if needed to remove oils ect
I know of some people that use a new freezer bag to place beans in, and then insert it into the Mylar bag - as a liner you could say

Mylar bags with one way valves are my preferred method of storage

I use those cans from Planetary Design (got them from Seattle Coffee Gear) that hav lids w/ one way valves. The lids can be pushed down to the level of the beans so there is little oxygen in the can.

But I wait 3-4 days before putting my beans in the canisters. When I put them in right away the coffee has an "off taste" that I imagine is from being trapped with the gases. As I understand it, the one-way valves are supposed to let the offensive gases out, but...

You got it. Tighten the lids just slightly - there is enough contact to keep air from getting in and it will be loose enough to let the pressure out.

If someone is doing a pole I vote for Mason jars, also I prefer the two-piece lids....
No oil on my beans...
